Mine is pretty much a daily driver. One morning I went to start it and it and it sounder real wierd
like no compression on a couple of cylinders or something. I finally got it started and once it warmed up and started firing on all cylinders

Someguy posted back in mid Feb, and says he has the same thing????? Wonder what kind of oil they have been using? Yea, a stuck valve, but on all 6 cylinders? Maybe we need to go back to some Wynns friction proofing for the stuck valves. Sea foam? He says the timing belts and timing marks are all good. Are we overthinking this? Carbon buildup?Strange on all six.

I thought about that for a moment too but way back in his first post,he mentioned it ran poorly then cleared up.Its really sounding like a lifter problem.

If it had to run and warm up to work right..... Could be sticking in the guides and free up when hot. Bet it wouldnt hurt to try to get sone sea foam on the valves and see if they would free up. All 6 lifters would really be strange unless real dirty oil.

It's unknown at this point.
I can only refer back to the original post."ran bad,missing then cleared up ok".This still makes me think of stuck lifters or valves.
Or,heaven forbid,my brother worked on it.

Still nothing back from the OP on this one. Weird, indeed!

For the life of me, I can't think of a single thing that would cause a catastrophic loss of compression on all 6 cylinders, simultaneously, without a serious !!!BANG!!!. The chances of both belts breaking at the same instant, bending ALL the valves on ALL cylinders, or holing ALL 6 pistons at the same time, are so infinitesimally small that it defies credulity. Heck, even MY legendary bad luck ain't THAT bad!

Similarly, the chances of both head gaskets blowing out across all the cylinders in each bank, is as likely as squadrons of pigs flying by in echelon formation.

There just HAS to be something else at the root of this. I, for one, would really like to know the outcome!

He said that the belts and timing marks all looked good. :) Sure wish I could lay hands on this one, but it is a long ways from Dunnellon. :lol:

The lifters is a purely mechanical push on the valves. They have to return by spring pressure. Either they are stuck in the valve guides, or the springs are broken is the only thing that I can see that can cause this. :?

"Checked and all cylinders are going up and down"

I have read through this thread several times.. and I have to smile every time I read this line.
I know what he means.. but it is still funny. There might be a engine somewhere that works that way... but doubtful. Back to the problem... we now have two Goldwings described in this thread
with grief and no resolution found or at least not reported.
Please check one

1. I found the problem... this is the cure for it... etc.
2. Still looking for the problem. It does not rank near the top of my spouse's important projects.
3. Computer died and I am not allowed in the public library
4. Gave up and sold it.
5. Gave up and junked it.

Just pick one please.

I offered to come down and take a look at it for him, but he decided not to. He is only about 40 miles from me.

Are we sure this has not been going on since April 1st., that's the only thing left that I could think of. Even if both cams belts broke at the same time it would leave some bent valves or piston holes but not all 12 valves or 6 pistons w/holes. Sure hope this saga ENDS SOON. :mrgreen:

I understand about the medical issues, been going thru that myself. My offer still stands to come down and help out a bit if you wish.

Hi

Just jumping in here.

Been reading this thread with interest. The bike ran fine the day before parked and the next morning it would not start? Right?

Battery good, spark good! Fuel coming through!

You say there is no compression.

I think it's the the lifters leaking off overnight. I think if you take out the plugs and crank it for an extended period the compression will start to read on the gauge. I had a similar problem with a ford Zetec engine. Overnight it would bleed off and would just crank in the morning for what seemed like ages! Once it started it ran really rough and eventually settled down. Used to be fine all day stopping and starting. Next morning was the same procedure. I ended up pulling the head and relaping the valves. 16 new lifters and it was as right as rain afterwards.

I would have a look at the lifters as it would appear that you have checked almost everything else.

Hope this helps

Rob

sounds exactly like the problem i am having. I will look at that as a possibility when I pull the valve covers.Any thoughts bstig60?

I believe that the problem is more that the valves are stuck open than the lifters not opening the valves. If "we" could get them to close, "we" could possibly get some compression. :) The lifters will open the valves, even partially if collapsed, but they will not close them. The springs have to do that. If the lifter was stuck, it could hold the valve open. If spring pressure is not enough to close then, then no compression. And if the intake valves are open all the time, then there is no fuel flow to the cylinder. Anyone agree with that?

Yes, you're right. If the lifters were bled dry, all the valves would be closed tight.

I still can't conceive of any situation that could result in all 12 valves sticking open at the same time, or all 12 lifters bleeding dry at the same instant (short of being entirely empty of oil). I think we're still missing something...

My bet is that everyone's over thinking it and the compression gauge doesn't work. I know he said it did, but still...

Testing the gauge on a known-working engine would determine that for sure...

If it was an aircraft engine and he has all the plugs out, I could understand no compression. :lol: :lol: :lol: But this makes no sense. There is still something out there that we don't know about yet. :roll:
